Tips for Visiting Morton Arboretum #

  • Plan a visit in autumn for peak fall color and go on a weekday morning to avoid weekend crowds that concentrate at the visitor center and popular trails.
  • Enter through the arboretum's main Route 53 entrance, pick up a map and follow the marked driving or walking loops to see the highlights rather than wandering aimlessly.
  • If you want to see popular seasonal features or guided tram tours, check and reserve those timed activities on the Arboretum's website in advance to avoid disappointment.
